is cl im. (01. a e-2s) This invention'relates a novel methods of andapparatus for automatically projecting a series of picture framesinresponse to the accompany.-

ing sound record.

' My present invention is a continuation in parti of my co-pendlngapplication Serial No.113,467,

filed November 30, 1936.' 7 .An important feature of modern newspape isthe comic section consisting of drawings depicting a continuity ofaction to form -a story, usually humorous in nature. 'Many childrenreg-' ularly follow the antics of-the comic characters and impose uponolder people. to read the expressions of these characters. My presentinvention is particularly directed to provide sound- .records printedintegral with the comic sections which records may readily be insertedin a novel reproducing machinefor obtaining an audible account of thecomic'action. The. audible rendition of comic sections or other featuresof a newspaper in a simple andinexpensive manner greatly enhancesthevalue of. these features to individuals, particularly to children, whocannot read. Major advantages of. this invention reside properseveringof the picture and sound strips in the mechanical recitation of comicsections to youngsters as well as in providing them with furtherentertainment in the use of the accompanying mechanism.

A further advantage of my present invention resides in the projection ofthe particular comic or picture frame which the accompanying sound isdescribing, and automatically shifting the pictures so that the nextsuccessive frame will be projected at the proper interval;The'particular frame being projected is maintained stationary during thedescription from the sound recitation therefor. At the end of'thedescription, a predetermined signal emanates from the recording which isused to automatically shift the projecting device to the next successivepicture frame. The enjoyment of the comic sections by the child isaccordingly further en-.

hanced, particularly if heordinariiy would have V dimculty in properlyfollowing the comic frames without selectiveprojection of the frames.

In a preferred .formof my invention, I print a series of sound strip s,-each containing a plurality of parallel sound tracks along one portionof the feature sheet containing the pictured story. The pictured storyis composed of a numher of picture frames'arranged into several stripsas is well known in the printing art. Lines and perforated markings areprovided to facilitate in from thesheet. The printingof th'sound trackin operation iof any picture in the paper.

strips upon the newspaper is similar to the print- A zinc plate isformed from the original sound tracks and the steps of printing thefacsimile of the sound tracks upon the sheet is similar to v establishedprinting procedure.

The reproduction apparatus for the printed soundstrips is identical tothat described in my co-pending application Serial No. 113,467hereinabove referredto. A notch is cut at a pre determined portion ofthe sound strip which actuates a relay for shifting the sound striptransverse to the scanning beam in order, to bring the next adjacentsound track. into scanning position. Where the strip is formedinto anend less belt, the shifting occurs at the joint be 4 tween the beginningand end of the belt. Acv cordingly at the moment one sound track iscompletely scanned, corresponding to one revolution of the endless.belt,.the scanning operation is continued at the beginning of the nextadjacent sound track.

A modification for reproducing the sound accompanying the picture framesresides in utilizing separate diskrecords instead of the printed soundstrips on the newspaper sheet. The

newspaper sound supplement records impressed I on paper mat withstandard printing machinery may be used for mechanical soundreproduction of the comic sections. Such records are described in myPatent- No. 2,063,870 issued December 8, 1936, and in my co-pendingapplica- 'tion Serial No. 113,182. filed November 28, 1936. Themechanicalrepnduction ap a atus is lws newspaper comic and picturesections.

Anotherobject'of my present invention is to provide novel methods forprojecting newspaper comic and picture sections together with soundreproduction "therefor and automatically shift:-

' ing thepicture frames inresponse to the sound recordings.-

The.

A further "object of my present invention is r to provide novelnewspaper comicor picture section projecting mechanism for selectivelyprojecting the picture frames in response to predetermined signals fromthe soimd reproduction thereof.

These and further objects of my present invention will become apparentin the following description taken in connection with the drawings, inwhich:

Figure 1 illustrates a preferred arrangement of a comic sheet containinga plurality of picture frames and sound tracks therefor.

Figure 2 illustrates a picture strip properly severed from the comicsheet.

Figure 3 illustrates a continuous picture strip built up from theindividual severed strips.

Figure 4 illustrates a sound strip properly severed from the comicsheet.

Figure 5 illustrates a continuous sound strip built up of the severedsound strips.

Figure 6 illustrates one form for carrying out my present invention.

Figures '7 and 8 illustrate modifications of apparatus for carrying outthe frame shifting operation.

Figure 9 illustrates a further modification for carrying out my presentinvention. 7

Figures 10, 11 and 12 are detailed views of Figure 9.

Figure 1 illustrates one arrangement for the comic strips and theaccompanying sound strips. The comic sheet 23 contains three strips 2|,22 and 23 containing four comic illustrations each. The squares numberedI to |2 represent a series of drawings or illustrations representing acontinuity of action similar to the well known comic or humorous stripsof newspaper sections.

Beneath the comic strips 2|, 22 and 23 are arranged three sound strips24, 25 and 26 containing a plurality of sound tracks 21. The number ofsound strips or sound tracks contained by each sound strip is optional.The sound strips 24, 26 and 26 may be arranged on a sheet separate fromthe comic strips 2|, 22 and 23. The application Serial No. 113,467hereinabove referred to contains other possible arrangements for thesound tracks and comic strips in a news- Pap r. In accordance with mypresent invention, the comic strips and the sound strips are each formedinto a single continuous strip for reproduction. To facilitate theformation of the corresponding continuous strips, I prefer to use aseries of perforations or score lines 28 about each of the strips 2| to26. The perforations or score lines 28 are indicated by dotted lines inFigure l. The lines 28 may be impressed upon the sheet simultaneouslywith the printing operation, although it'is not essential. Theperforation or scoring along lines 28 may be replaced by correspondingprinted lines along which the operator will shear in separating theindividual strips 2| to 26. I prefer to employ perforations or scorelines particularly for the lines 28 bounding the sound strips 24, 25.and 26 in order to accurately predetermine the scanning position for thesound tracks 21 as described in the Ser. No. 113,467 applicationreferred to. A score line or guide line 28 is placed adjacent one edgeof the comic strips 2|, 22 and 23 to facilitate in the alignment of theframes to |2 at the proper separation distances, as will be described. Afurther line 36 is formed to define the outer edges of the sound tracksand to keep the sound tracks 21- within the boundary of the sheet 20.

Figure 2 illustrates one of the comic strips 22 correctly severed fromthe sheet 28 preparatory to formation into the continuous strip with theother frames. The top and bottom boundary lines 23 are drawn in dottedlines to illustrate the severing along corresponding lines on sheet 23.Line 23 corresponds to the same line on sheet 23 at the left portion ofthe strip 22. Edge 29 is separated from the left edge 3| of frame 6 by adistance equal to the separation between the adjacent frames of thecomic strips. The right edge 32 of the comic strip 22 is separated byany suitable distance from the corresponding right edge 33 of theadjacent frame 8. The portion of the strip 22 between edges 32 and 33 isused as the underlap portion in forming the continuous strip.

Figure 3 illustrates the continuous strip 34 formed of the picture orcomic frame strips 2|, 22 and 23. These strips are formed by pasting.the edge 23 of strip 22 adjacent the outer edge of frame 4, thecorresponding end 32' of strip 2| being pasted beneath the frame 5. Theedge 23 serves as an accurate guide for forming the strips 2| and 22 inexact linear relationship, and the spacing between the edge 29 and line3| automatically separates frame 4 and 5 by the same distance which theother frames are separated. In a similar manner, the strip 23 is securedto strip 22, frame 9 being pasted upon the underlap portion 32 to 33 ofstrip 22. If more than three strips containing frames are employed, theyare similarly attached in series to form the comic or picture strip 34to be projected by the apparatus of my present invention. I prefer toform the picture strip 34 into an endless belt form for projectionthereof. This i is accomplished by pasting the edge 29 adjacent thefirst frame I upon the underlap portion of the last strip 23 against thebottom edge of the last frame I 2.

Figure 4 illustrates sound strip 26 severed from the newspaper sheet 2|!having the bounding edges 28, 36 and 3|. The perforated scored edges 28are parallel to the sound tracks 21 and are spaced in a predeterminedrelation with respect to these sound tracks. The underlap region for thesound strip 26 corresponds to the portion between the line 36 definingthe right edge of the sound tracks 21, and the edge 3| of the strip 26.This underlap region is shown darkened although it is not necessary toso arrange the strip. The sound tracks 21 correspond to the voice ordescrlption of the action or pictures represented in the frames to l2.The sound tracks 21 are printed upon the sound strip by printing methodswell known in the art. Variable area or variable density recording maybe used, variable area recording being preferable for the newspaperwork.

Figure 5 illustrates the continuous sound strip 36 formed of theindividual soundstrips 24, and 26 by pasting the left end ofeachsuccessive strip upon the underlap portions of the right end of thepreceding strip. The sound tracks 21 communicate across the adjacentstrips to form a plurality of continuous and parallel sound tracks oflength equal to the whole length of the strip 36. The sound strip 36 isequivalent to the corresponding strip illustrated in Figure 5 of theabove-mentioned application Serial No. 113,467. An endless strip isformed of strip 36 by pasting the top edge 23 of strip 24 adjacent edgeof strip 26 upon the underlapportion of strip 26.

Anotch 3! is cut out at the end of the last track in strip 26. Thisnotch is used to shift the sound track scanning mechanism to the nextadjacent sound track when the apparatus arsaaoe has scanned one wholesound track so as to constrip I. reasonably taut. 'lhe electro-opticaltinue the upon the ,next adjacent sound track ofthe endless-form of thestrip II. The

description for each frame, a characteristic sound or whistle isproduced on the sound tracks to mark the end of the projection for thatparticular frame and initiate the shifting operation to quickly bringthe next frame into view.- The continuity ofspeech'continues afterthewhistle or note is performed and the next frame is in view.Irhavemarked darkened areas I! upon the sound strips to illustrate therandom portions of these strips at which the sound signals r Thesepositions correspond may be positioned. to the shifting of thesuccessive frames in a pre-- determined relationship with the speechbeing reproduced.

Figure 6 illustrates one formof apparatus for carrying out theprinciples of my present invention. The picture strip 34 formed in anendless belt is arranged about pulleys ll and v ll.

The position of top pulley ll is adjustable by ex- 36 tension wire 42 soas to maintain strip reasonably taut. .Strip 34 passes throughprojection apparatus 43. Strip 34 passes in front of an opening in theoptical system 44 equallto the width of one picture frame.' A guideplate 0 guides the strip ll {against one side of the optical system H.Plate 45 is preferably lightly biased by springs 45 against the stripll. Plate .45 is preferably opaque toassist in the sharp v projection ofthe pictures. a 45 The illustrated optical system 44 contains twoelectric light sources. I! for illuminating the "frame on the'strip 34opposite the opening in the enclosure 44. A lens system 48 projects theV illuminated picture frame upon a ground glass 50 screen '49 inenlarged form. The arrangement of the lenses and the direction of feedof the picture strip 3! is-designed to produce an en- 7 larged image onthe screen 4! in upright relation for suitable viewing frrom the frontof the '5 projection apparatus ".1 It is to be'imderstood so the pictureframe may be viewed directly without optical enlargement thereof so thatthe youngsters being entertained will know exactly which frame is beingtalked about during the sound accompaniment. My present invention is 5directed towardtheautomatic shifting of the successive frames into viewin synchronism with the sound reproduction thereof, and not to theparticularmethod'of viewing the pictures.

Thesound strip 86 is driven ata substantially constant speed. when onesoundtrack is completely scanned, the notch 31 actuatesshiftlngmechanism not illustrated to automatically shiftihe 1Q scanning over tothe next adjacent sound track so as to continue thescanning operation ina continuous'manner. The sound scanning shiftingmechanismis described indetail lnmy copending application Serial No. 1.18.487 hereinllif abovereferred to and is omitted from the illuh tration to simplify thedisclosure. The electrical output from scanner I1 is connected toamplifier i 80. The output terminals ll of amplifier con-Inecttoaloudspeaker 62 foracousticallytrans- 20 latingthe electricalsignals as sound at the pro- 1 jection apparatus 43 in conjunction withthe picture being used.

The apparatus of Figure 8 illustrates a common motor I for driving boththe sound and projec- 25 tion apparatus of my praent invention. Thewhole apparatus maybe embodied'in a common I housing. The motor I isenergized from elec-' trical supply line H and is continuously rotatedat a substantially constant rate. Reduction gearmg ii'connects thebevelgears 66 to the motor .at' a predetermined reduction ratio for movingsound strip 36 at the predetermined speed. The

reduction gearing "also connects motor I to the frame shifting mechanismit for shifting the picture strip 34 between frames in response to anelectrical signal as will be described hereinafter. e w r A positiveclutch 8'|ll is used to connect the picture strip 34 drive with theshaft 10. of the 40 clutch portion 88 along shaft II for engaging or 45disen aging with the clutch portion G1. Yoke 'll" Y is integrallyattached to an armature 12 coacting with a relay II. A pivot Ilis placedbetween the yoke 1i and armature II. A spring I! mechanically biases theclutch 01- into open posi-r' a tion. r

clutch "48 when therelay'llis d and simultaneously engages the brake 11to stop Q a therotation of the-beveled gears li after'the frame shiftingoperation hasbeen performed.

5 The frame shifting operation is performed when the predeterminednoteor sound portion 38 occurs on the sound tracks hereinabove deasscribed. This note maybe a constant frequency signal such as a thousandcycles. When'a' pure note section 38 passes opposite. scanner 51, a cor-V responding electrical. current is' produced by amplifier 60. Outputterminals "of amplifier 1.

"6. are connected to a'fllter l. which isadjusted to the.'freque'ncy'ofathe predetermined note, for' example a thousand cycles. Adifferent fre- 'quiency can be used-but onethousand cyclm is chosen forillustration- Filter OI is tuned to (I suilicient gass a thousand cyclescurrent to the relay 33 and reject other frequency currents in a mannerwell known in the art. The relay 13 will accordingly be energized duringthe interval of the predetermined thousand cycle note portion 38 on thesound tracks and attract armature I2. By attracting armature I2, brakeI1 is released and the positive clutch 6'I-68 is engaged to drive thepicture strip 34 from the motor 63 through the gear box 65. The frameshifting operation accordingly occurs while armature I2 is attracted torelay 13. The time required for executing the frame shifting operationdepends upon the width of the frame and the rate of feed of the strip34. In this modification, the length of the sound portion 38 on thesound tracks is made long enough to render the thousand cycle note forthe time required to execute the frame shifting operation.

The relay I3 may operate directly from the alternating current thousandcycle note output of filter 88. However, a direct current relay may beused instead if the filter current is rectified. The predetermined notecorresponding to sound portions 38 to effect the frame shiftingoperation may be a pleasant whistle or sound for the listener to hearduring the frame shifting which may take less than two seconds toeifect. However, by employing a note absorber 8| across the output SI ofamplifier 68 sharply tuned to absorb or attenuate the thousand cyclenote, the whistle may be practically eliminated from the output of loudspeaker 62. Such a sharp note absorber or filter 8i would not materiallyaffect the intelligibility of the sound reproduction. Other notes may becombined with the predetermined thousand cycle note to form a pleasantsound efiect at speaker 62 without a note absorber 8|. The note filter88 need only respond to a predominant frequency such as a thousandcycles and will have sufficient energy to maintain armature I2 attractedduring the shifting cycle.

Figure 7 illustrates a modification for the frame shifting mechanismresponsive to the filter 88 signals. A separate motor 82 energized from'power lines 83 is used for the frame shifting mechanism. A pinion 84,directly connected to motor 82 drives a gear 85 which is connected tothe friction pulley 86 for driving the picture strip 34. A roller 81presses the picture strip 34 against drive roller 86.

A disk 88 is secured to the gear 85 drive. The periphery of the disk 88contains a notch 89. A lever 98 contains a projection 9| which coactswith the periphery of disk 88. Lever 98 is me-,

chanically biased against the periphery of disk 88 by spring 82. Theprojection 3i engages with the notch 89 and holds the disk 88 againstrotation during this engagement.

The motor 82 is designed to permit stalling of its armature withoutover-heating. The motor 82 drives the picture strip 34 until theprojection v SI stops the rotation of disk 88. When a signal impulse isreceived by relay I3, it attracts the armature portion 93 away from disk88, releasing the engagement thereof. Disk 88 is accordingly permittedto revolve for one revolution which is designed to be equal to the frameshifting re quirements. The signal impulse at relay I3 in thismodification need only be of relatively short duration as compared tothe modification of Figure 6. The signal impulse disengages the lever 38and disk 88, permitting the disk to rotate. Before one revolution ofdisk 88, the signal is completed and the motion of the disk is arrestedduring the projection of the particular frame in view.

The motor 82 accordingly is continuously energized from the power lines83 but acts to revolve drive pulley 86 only for the frame shiftingmovements as will now be evident. The frame shifting signal of themodification of Figure 7 may be of only a relatively short duration. Toaccurately differentiate the thousand cycle note or signal from any ofthe voice frequencies, asharply tuned filter may be used in conjunctionwith a marginal responsive relay operation well known in the electricalart. The printed signal corresponding to areas 38 of the sound tracksmay be made of greater amplitude for actuating the marginally responsiverelay corresponding to relay I3.

Figure 8 illustrates a further modification for efi'ectlng the frameshifting operation in response to the signal operated relay I3.

except that a spring wound motor 34 is used instead of the electricalmotor 82. The spring wound motor 94 contains a gear 85 which engageswith pinion 96 to continuously tend to drive the friction pulley 86directly connected thereto, for effecting the movement of. strip 34. Theprojection 9| of lever 98 cooperates with notch 83 to maintain theindividual frames in view until a frame shifting signal current flowsinto relay I3 to attract the armature 33 for disengaging disk 88 andpermitting it to revolve for one frame shifting revolution. Thismodification employing a spring motor is relatively inexpensive tomanufacture and would be employed for the cheaper models for children.

Figure 9 illustrates a further modification for The mechanism ,of thismodification is similar to that of Figure 7 performing the frameshifting operation in response to the signal areas 38 on the soundtracks. The projection mechanism 43 for projecting a frame of soundstrip 34 upon the ground glass screen 49 contains the optical system 44similar to that of Figure 6. The sound reproducing mechanism 58 isschematically represented similar to that of Figure 6, like numeralsreferring to similar components.

Modifications in this figure specifically reside in the mechanism forfeeding and guiding the picture strip 34, and in the mechanism forperforming the frame shifting thereof. Common motor drive 63 isconnected to the reduction gearing box 65 which directly drives thebeveled gears 66 at a continuous rate for operating the sound recordingstrip 36. The picture strip drive is transmitted through the shaft I8projecting from gear box 65. The shaft I8 is connected to a frictionclutch I88, the output of which is connected to a torsion spring I8I.Torsion spring IN is in effect an accumulating spring which is wound upwhen the torsional potential energy stored up in the spring causes thefriction clutch I88 to slip. Enough torsional energy is stored up inspring m to move the picture strip at through at least one frameshifting operation. Torsional spring I8I is directly connected tobeveled gears I82 which drive gear I83 connected to gear I84.

, Gear I84 is connected to the drive pulley I85 for I85 similar to themodifications of Figures 7 and 8 where the electric and spring motorsrespectively create a potential drive condition between frame shiftingoperations. The projection I81 at the end of lever I00 engages one ofthe notches I00 of the disk I00 until relay ll attracts armature'il0 oflever I00 to unlock thedisk I00 to permitit to rotate sufficiently forone frame shifting operation. The driving of the picture strip 34 occursduring the rotation'of disk I08 by the torsional spring IOI'energization. Two notches are arranged on disk I06,Q180 apart so thatone revolution of disk I00 corresponds to two frame shifting operations.Still more notches may be used for correspondingly more shiftings perrevolution of disk I06, the determining factor naturally being the ratioof diameters between disk I06, drive pulley I and the length of eachframe.

A pawl and ratchet arrangement III-III is used to prevent the torsionalspring IIII from unwinding when the clutch I00 starts to slip at thefully wound condition thereof. Figure 11 shows an end view of theratchet and pawl I II-II2 arrangement for holding the torsional springin fully wound condition after being wound up across the frictionalclutch I00 by the shaft I0 operating through the gear box 85 from motor'83. When spring I M gives up some of its stored .energy for a filmshifting operation or two, the

clutch I00 automatically reengages to continue to wind up spring IOIsince its stored energy becomes insufllcient to cause the clutch toslip. In this manner, the frame shifting energization is automaticallymaintained without a separate motor drive. v

The picture strip 04 of'Figure 9 is driven by two coacting belts H3 andH4 in frictional engagement with the endless strip 34. Belts H3 and H4are arranged on pulleys I05 and H5 parallel to the frame shiftingdirection. Belts I I3 and I I4 are preferably operated with a positivedriving connection. 'A suitable positive drive is a sprocket drive.Figure is a partial illustration showing the sprocket holes H8 in thesides of the friction belt I I4 engaging the sprocket idler pulley H5.The sprocket holes extend beyond the width of the picture strip- 34 sothat the sprocket teeth of the pulleys will not interfere with thepicture strip 34. A gear I20 for driving the belt system H3 is engagedwith pulley I04 for a direct driving condition.

A series of pressure plates III are held against the internal surfacesof the friction belts H3 and H4 by springs II8. Figure 12 is acrosssectional view taken along I2I2 of Figure 9 showing therelationship between the outer pressure plates I I1 holding together thefriction belts II3--I I4 which hold in engagement the picture strip 34.The picture strip 34 is accordingly driven in a positive manner throughthe accumulating torsion spring IOI whenever relay I3 is energized topermit the disk I05 to advance by one notch. The frame shiftingoperation is accordingly automatically performed during a suitablesignal impulse passing through filter 80 to a relay 13 when apredetermined area 30 of the sound strip is being scanned at the soundrecording apparatus 50. s
